Kinesin light chain 4 as a new target for lung cancer chemoresistance via targeted inhibition of checkpoint kinases in the DNA repair network. Cell Death Dis 2020; 11:398. [PMID: 32457423 PMCID: PMC7250887 DOI: 10.1038/s41419-020-2592-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2019] [Revised: 05/05/2020] [Accepted: 05/06/2020] [Indexed: 02/07/2023]
Abstract
The poor therapeutic efficacy of non-small cell lung cancer (NSCLC) is partly attributed to the acquisition of chemoresistance. To investigate the mechanism underlying this resistance, we examined the potential link between kinesin light chain 4 (KLC4), which we have previously reported to be associated with radioresistance in NSCLC, and sensitivity to chemotherapy in human lung cancer cell lines. KLC4 protein levels in lung cancer cells correlated with the degree of chemoresistance to cisplatin treatment. Furthermore, KLC4 silencing enhanced the cytotoxic effect of cisplatin by promoting DNA double-strand breaks and apoptosis. These effects were mediated by interaction with the checkpoint kinase CHK2, as KLC4 knockdown increased CHK2 activation, which was further enhanced in combination with cisplatin treatment. In addition, KLC4 and CHEK2 expression levels showed negative correlation in lung tumor samples from patients, and KLC4 overexpression correlated negatively with survival. Our results indicate a novel link between the KLC4 and CHK2 pathways regulating DNA damage response in chemoresistance, and highlight KLC4 as a candidate for developing lung cancer-specific drugs and customized targeted molecular therapy.

Adv Drug Deliv Rev 2020; 163-164:3-18. [PMID: 32229271 DOI: 10.1016/j.addr.2020.03.004] [Citation(s) in RCA: 49] [Impact Index Per Article: 12.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2019] [Revised: 03/20/2020] [Accepted: 03/24/2020] [Indexed: 12/23/2022]
Abstract
Hyperthermia therapy is a potent enhancer of chemotherapy and radiotherapy. In particular, microwave (MW) and radiofrequency (RF) hyperthermia devices provide a variety of heating approaches that can treat most cancers regardless the size. This review introduces the physics of MW/RF hyperthermia, the current state-of-the-art systems for both localized and regional heating, and recent advancements in hyperthermia treatment guidance using real-time computational simulations and magnetic resonance thermometry. Clinical trials involving RF/MW hyperthermia as adjuvant for chemotherapy are also presented per anatomical site. These studies favor the use of adjuvant hyperthermia since it significantly improves curative and palliative clinical outcomes. The main challenge of hyperthermia is the distribution of state-of-the-art heating systems. Nevertheless, we anticipate that recent technology advances will expand the use of hyperthermia to chemotherapy centers for enhanced drug delivery. These new technologies hold great promise not only for (image-guided) perfusion modulation and sensitization for cytotoxic drugs, but also for local delivery of various compounds using thermosensitive liposomes.

Abstract
The long noncoding RNA (lncRNA) MIR503HG has been shown to play an important role in cancer development. The aim of the present study was to investigate the potential roles of MIR503HG in the proliferation and apoptosis of non-small cell lung cancer cell (NSCLC). We used short hairpin RNA (shRNA) against MIR503HG to knock down and vector containing full length of MIR503HG to overexpress MIR503HG in NSCLC cells. The expression of MIR503HG in NSCLC tissues and cells was detected and the effects of MIR503HG on the cell proliferation and apoptosis were determined. Results showed that the expression of MIR503HG was significantly upregulated in NSCLC tissues compared with adjacent tissues. We found that downregulation of MIR503HG could clearly suppressed cell proliferation and cell cycle progression. Moreover, MIR503HG knockdown also promoted apoptosis of NSCLC cells. As expected, overexpression of MIR503HG significantly promoted cell proliferation and inhibited cell apoptosis in NSCLC NCI-H1975 cells. We predicted and verified miR-489-3p and miR-625-5p as the direct targets of MIR503HG by bioinformatics analysis and luciferase reporter assay. Mechanically, MIR503HG negatively regulated miR-489-3p and miR-625-5p expressions in NSCLC cells. Moreover, downregulation of miR-489-3p and miR-625-5p weaken the decreased cell proliferation and increased apoptosis of A549 cells after MIR503HG knocking down. In conclusion, knockdown of MIR503HG suppressed proliferation and promoted apoptosis of NSCLC cells through regulating miR-489-3p and miR-625-5p. Our findings of this study suggested that MIR503HG could be a potential therapeutic target for NSCLC development.

Long non-coding RNA FLVCR1-AS1 contributes to the proliferation and invasion of lung cancer by sponging miR-573 to upregulate the expression of E2F transcription factor 3.

Abstract
Lung cancer is one of the most common causes of cancer-related death all over the world. In recent years, long non-coding RNAs (lncRNAs) have been reported to play critical roles in the development and progression of human malignancies. In the present study, we aimed to study the role and mechanism of FLVCR1-AS1 in human non-small cell lung cancer (NSCLC). Results revealed that FLVCR1-AS1 was markedly upregulated in NSCLC tissues and cell lines. Knockdown of FLVCR1-AS1 significantly inhibited the proliferation, migration, invasion and promoted apoptosis of NSCLC cells, and suppressed tumor growth of NSCLC in vivo. Moreover, we explored regulatory mechanism, and found that FLVCR1-AS1 functioned as a competing endogenous RNA (ceRNA) by directly binding to miRNA-573, and E2F transcription factor 3 (E2F3) was identified as a down-stream target of miR-573. FLVCR1-AS1 positively regulated E2F3 expression through inhibiting miR-573 in NSCLC cells. Our findings suggested that FLVCR1-AS1/miR-573/E2F3 axis was an important signaling pathway in mediating tumorigenesis and progression of NSCLC, and further indicated that FLVCR1-AS1 could be a novel diagnostic biomarker and therapeutic target for NSCLC.

Abstract
Extracranial stereotactic radiotherapy has developed considerably in recent years and is now an important part of the therapeutic alternatives to be offered to patients with cancer. It offers opportunities that have progressively led physicians to reconsider the therapeutic strategy, for example in the case of local recurrence in irradiated territory or oligometastatic disease. The literature on the subject is rich but, yet, there is no real consensus on therapeutic indications. This is largely due to the lack of prospective, randomized studies that have evaluated this technique with sufficient recoil. We propose a review of the literature on the technical aspects and indications of extracranial stereotactic radiotherapy.

Abstract
Resistance to chemotherapeutic drugs is a major obstacle in non-small cell lung cancer (NSCLC) therapy. The molecular determinants of NSCLC resistance to doxorubicin are unknown. In the present study, we investigated whether topoisomerase IIβ binding protein 1 (TopBP1) was involved in the chemoresistance to doxorubicin in NSCLC cancer. We found that p53-deficient lung cancer cells (NCI-H1299) displayed the greatest resistance to doxorubicin compared with NCI-H358, A549, and HCC827 cells with p53 expression. The expression of TopBP1 was significantly higher in NCI-H1299 cells than the other three tumor cell lines. In addition, TopBP1 knockdown with specific small interfering RNA in NCI-H1299 cells enhanced the doxorubicin chemosensitivity and decreased the expression of p53 in the presence of doxorubicin. After doxorubicin administration, co-immunoprecipitation assay showed that TopBP1 promoted the expression of p53 in NCI-H1299 cells. These results for the first time demonstrated that TopBP1 plays an important role in NSCLC chemoresistance via upregulation of p53. Therefore, inhibition of TopBP1, in combination with chemotherapy, may represent a novel strategy for the treatment of chemotherapy-resistant NSCLC.
